ColorFabb (Venlo, The Netherlands) has introduced XT-CF20, an additive manufacturing filament based on the Amphora 3D copolyester (from Eastman Chemical) reinforced with carbon fiber at loadings of up to 20%. XT-CF20, which prints with a matte finish, offers a flex modulus of 6.2 GPa, strain at break of 8-10%, Tg of 80°C, high melt strength, high melt viscosity, low odor, compatibility with several 3D printing platforms and diameters of 1.75 mm or 2.85 mm. ColorFabb notes that carbon fiber's abrasiveness requires use of stainless steel or hardened copper alloy nozzles on printing heads.
